Everyone that joins ICOs, bounties or airdrops might recently be receiving some emails purported to be from a project administrators informing you of that your earlier contact of the support has been escalated and you need to be a certain sum of bitcoin or ethereum in order to abade the problem otherwise, you lose your investment or earnings.
It is a scam. Beware!!!
Of course, it is a scam. Who falls for that?
There are way harder to understand scams. This one is like "hello i want to scam you, can you give me your money".
I haven't received that kind of message yet on so many ICO and airdrops I've promoted in the past, can you name those altcoins, any ICO that will do that can be tagged as a scam, we just have to ignore this and contact the team of the ICO that sent this, of course, they will deny this, they only target newbies.
